Technical field
The present invention relates to steel-making continuous casting technical field, more particularly to a kind of on-line measurement at a high speed conveying to have cut continuous casting billet long
The method and system of degree.
Background technology
In steel-making continuous casting field, continuous casting billet (referred to as " is drawn in the presence of withdrawal straightening machine with the casting speed of 0.5~3m/min
Speed ") advanced on roller-way, then it cuts into required length during traveling by sizing cutting device, through its cutting
Continuous casting billet out has cut continuous casting billet, and through ejection roller way, (20~30m/min) is delivered to subsequent processing at a high speed again.
Because sizing cutting device has measurement error, mechanical delay, return, cause and cut continuous casting billet
It is different in size, directly affects the product quality and cost of conticaster.
With the change and the raising to continuous casting billet quality requirement in market, cost pressure is increasing, therefore to the company of having cut
The required precision of strand length also more and more higher, particularly with the conticaster of hot delivering technology of CC billets technique to be implemented for, it is proposed that
Tightened up requirement：One is that the precision for having cut continuous casting billet length will be controlled within 0~10mm；Two is that will exceed the scope
Cutting continuous casting billet and identifying prevents it from entering subsequent processing；Three is that low land reduces the thermal loss for having cut continuous casting billet as far as possible, will
It rapidly sends into hot-rolled process.Therefore, being highly desirable to having cut continuous casting billet before subsequent processing is sent into its length weight
Newly carry out one-shot measurement.
However, there are various defects in some current measuring methods and device：Have plenty of the length measured to miss
Difference is larger；To have plenty of first allow and cut continuous casting billet and stop on ejection roller way, it is to be measured it is complete after will cut continuous casting billet again and be transported away, and
This has scattered and disappeared and more has cut continuous casting billet heat again.It has the disadvantage all to be difficult to meet technological requirement.In consideration of it, urgently proposing a kind of
The method and system for having cut continuous casting billet length that on-line measurement is conveyed at a high speed.
